passive-mode
To configure the required mode to initiate an IP connection, use the passive-mode option. To enable passive mode for the FCIP interface, use the no form of the option.
passive-mode
no passive-mode
Syntax Description
Defaults
Disabled
Command Modes
Configuration mode
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.1(1).
Usage Guidelines
Access this command from the switch(config-if)# submode.
By default, the active mode is enabled to actively attempt an IP connection.
If you enable the passive mode, the switch does not initiate a TCP connection and merely waits for the peer to connect to it.
Examples
switch# config tswitch(config)# interface fcip 1switch(config-if)# passive-modeRelated Commandss
show interface fcip
Displays an interface configuration for a specified FCIP interface.
peer-info
To configure the peer information for the FCIP interface, use the passive-mode option. To disable the passive mode for the FCIP interface, use the no form of the option.

Command Modes
Configuration mode
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.1(1).
Usage Guidelines
Access this command from the switch(config-if)# submode.
The basic FCIP configuration uses the peer's IP address to configure the peer information. You can also use the peer's port number, port profile ID, or port WWN to configure the peer information. If you do not specify a port, the default 3225 port number is used to establish connection.
Examples
The following command assigns an IP address to configure the peer information. Since no port is specified, the default port number, 3225, is used.
switch(config-if)# peer-info ipaddr 10.1.1.1The following command deletes the assigned peer port information.
switch(config-if)# no peer-info ipaddr 10.10.1.1The following command assigns the IP address and sets the peer TCP port to 3000. The valid port number range is from 0 to 65535.
switch(config-if)# peer-info ipaddr 10.1.1.1 port 3000The following command deletes the assigned peer port information.
switch(config-if)# no peer-info ipaddr 10.1.1.1 port 2000The following command assigns the peer profile ID to connect to 20. The valid range is from 1 to 255
switch(config-if)# peer-info profile_id 20The following command deletes the assigned peer profile ID information.
switch(config-if)# no peer-info profile_id 500Related Commandss
show interface fcip
Displays an interface configuration for a specified FCIP interface.
ping
To diagnose basic network connectivity, use the ping (packet internet groper) command in EXEC mode.
ping {host-name | system-address}
Syntax Description
host-name
Host name of system to ping. Maximum length is 64 characters.
system-address
Address of system to ping.
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
The ping program sends an echo request packet to an address, and then awaits a reply. The ping output can help you evaluate path-to-host reliability, delays over the path, and whether the host can be reached or is functioning.
Verify connectivity to the TFTP server using the ping command.
To abnormally terminate a ping session, type the Ctrl-C escape sequence
Examples
The following example pings system 192.168.7.27.
switch# ping 192.168.7.27PING 192.168.7.27 (192.168.7.27): 56 data bytes64 bytes from 192.168.7.27: icmp_seq=0 ttl=255 time=0.4 ms64 bytes from 192.168.7.27: icmp_seq=1 ttl=255 time=0.2 ms64 bytes from 192.168.7.27: icmp_seq=2 ttl=255 time=0.2 ms64 bytes from 192.168.7.27: icmp_seq=3 ttl=255 time=0.2 ms--- 192.168.7.27 ping statistics ---13 packets transmitted, 13 packets received, 0% packet lossround-trip min/avg/max = 0.2/0.2/0.4 msport
To assign the port number of a Gigabit Ethernet interface to the FCIP profile, use the port command.
port number

Syntax Description
Defaults
Disabled
Command Modes
Configuration mode—fcip profile submode
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.1(1).
Usage Guidelines
Associates the profile with the assigned local port number. If a port number is not assigned for a FCIP profile, the default TCP port 3225 is used.
